EN Automatic Transfer Switch (ATS) Quick Start Guide
1. EN Introduction This ATS product is designed with two independent power inlets to supply power to the load from a primary power source. Should primary power source fail, the secondary will automatically back up the connected equipment without any interruption. The transfer time from one line to another is seamless to the connected equipment. After switching to a secondary power source, the ATS can also switch power back to the primary input when power to the primary input is restored.
. Important Safety Warnings Before using the unit, please read all instructions and cautionary markings on the unit, this manual and the batteries. EN WARNING!! The ATS must be connected to earth when in use. In line with current regulations, only use the cables that have been supplied with the machine. The power supply socket must be easily accessible to the operator. WARNING!! The ATS has been designed exclusively to operate indoors.
Indication type EN Priority setting LEDs LED description LED status Source A is priority OFF Source B is priority OFF OFF Inlet A has no power input OFF ON Inlet A has power input, and power is OK OFF Flashing Inlet A has power input, but power is out of SPEC OFF OFF Inlet B has no power input OFF ON Inlet B has power, and power is OK OFF Flashing Inlet B has power input, but power is out of SPEC OFF Power A is output OFF Power B is output OFF NO OUTPUT OFF OFF Alarm not prese
. Installation NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. Mounting the Unit The unit can be mounted in a standard 19" rack. Fasten the mounting brackets to the unit using the screws provided. With brackets attached securely, users can mount the unit in a standard 19" rack as shown below.
. EN Operation Power On/Off Put the input power switch in “ON” position. The output will then be supplied by the source set as selected. Setting priority of power source It is possible to set the power source preference to supply the output by pushing the button of “source preference selector”. The default power source is “Source A”. 7.
Contact Ports The contacts port is formed using six (6) pins numbered from left to right (see fig. 1), which can be connected to an external monitoring system (such as a BMS) in order to monitor the operational status of the ATS. The external equipment must respect the voltage and current characteristics of contacts port. Fig. 1: Focus on contacts port. The contacts port provides the following pins: Pin 1: common contact.
. Trouble Shooting Use the table below to solve minor problems. Problem EN The ATS with the mains voltage present, does don’t turn on. (The LEDs does not flash and no alarm sounds.) Possible Cause Solution No connection with input plugs Connect the mains to the input plugs as indicated in the installation section. Input switch in “OFF” position Turn the input switches in “ON” position.

. Appendix: Input Voltage and Frequency Thresholds EN FUNCTION Acceptable input voltage range for Source A Return voltage point for Source A Acceptable input voltage range for Source B Return voltage point for Source A Acceptable input frequency for Source A Acceptable input frequency for Source B DESCRIPTION Source A will be power source during this range. When input voltage of source A is beyond this range, ATS will automatically switch to power from Source B.
